\ SMOK -"House AND runnnconomznn v Be it known that I, EDWARD FnAn'noAn a citizen of the United States, residing at 7, Philadelphia, in the county (if Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Smoke-- Houses and Fuel-'Economi'zers, of which the following is a specification. a

I through every part of the inclosu're'.

' lower portlon with a furnace e invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set, forth, illustrated and claimed. i a

In the drawings hereto attached :"-Fi'g"1ire 1 is a vertical section of a smoke house and appliances embodying the invention. Fig. 2 is an enlarged sectional view of the fan by means of which the smoke is caused to circulate through the 'house and returned to the furnace. Fig. 3 is an enlarged sectional view of. the smoke gatherer. Fig. 4 is an enlarged sectional view on the line H of Fig. 1. Fig. 5 is an enlarged sectional view on the line y-y of Fig. 1. Fig. 6 is an end view of the furnace.

Corresponding and like arts are referred to the following description, and indicated in all the views of the drawings by' the same reference characters.

The numeral 1 designates a smoke housewhich is prov ded at its top with the usual cupola or ventilating projection2 and in its 3 for burning sawdust, wood or other fuel for generating smoke which is utilized for curing purposes .in the treatment of food such as meat and fish. A pipe 4 extends through a side of, the ventilating projection 2 and has a dependingl'portion upon which is fitted a hood 5 whic serves the double purpose of a smoke gatherer and a valve for closing the lower end of the ventilating projection 2.]

I of the The hood 5 isof conical form and is verti- A collar 6 is formed at the center of the hood 5 and is arranged toslide upon the depending or vertical portion I ipe 4. Flexible connections 7 are attached at one of their ends to the hood 5 and passjover pulleys 8 at the top of the projection 2 and-have weights 9 at their lower Specification of'Izetteis Patent.

- the invention appertains, and while described the principle of operation of the Patented 315L 23; 1915.

ends to counterbalance the hood and assist in the adjusting of the hood and the holdiiig' of the same in the ad usted position. When a strong draft is required as when starting the fire,- the hood is lowered so the smoke and "roducts of combustionmay pass out thioug the openings in the side of the projection (if cupola 2.

The furnace 3 has two compartments 13 and 14, the upper compartment '13 consti puting the combustion chamber and the ower compartment 14 corresponding .with' the-ash pit. i branch pi e 15 connects the a vertical pip 16; A branch 17 connects the upper cdiiipait'meiit-lir ,o the furnace with fii ieia Each'of' the branch pipes 15 and 17- is rovided with a damper 18 such as indipa' d nest iany n Figs 5. The pipe 16 connects atits upper end with the cas ng of a fan 19 and the pipe 4 also connects with located in the length of the pipe {1 and may be regulated to admit fresh air when required. j .X- i

When starting the fire in the furnace, the

hood 5 is lowered, so as to establish free COIIlIIl11I11C2,tl0Il between the ventilating p'ro- -jection 2 and the house or structure 1, and

*into the combustion chamber 13 through thepipes 16 and 15 thereby producing a saving in the consumption of fuel since the is used over and over. 7 h A From the foregoing description, taken in connection- .with the accompanying drawings,-the advanta es' of the construction and of the method o I have sides of the ,70 compartment 14 of. thepfurnace with the the. casing of the fan 19. A damper 20 is i lot ried to the furnace through the pipes 4,-16

smoke its operation. will be readilv apparent to those skilled in the art to which v invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and

that such changes may be made when desired as are within the scope of the invention as claimed.

Having I Y may be regulated. p

-2. In combination, a smoke house provided in its upper portion with a ventilating projection, a furnace'located in the lower portion of the smoke house, a hood for closing the ventilating projection, means for adjusting such-hood and holding it in' the adjusted position, a

pipe establishing communication between the hood and furthus described the invention, what is claimed as new is:-

means ing a depending portion and provided in its I length with a damper, a hood for closing the ventilating projection and slidable upon the depending portion of the said pipe, means for adjusting the hood vertically, a vertical pipe connected at its lower end with the furnace, a damper for regulating the discharge from the vertical pipe into the furnace and a fan in the length of the vertical pipe for creating a positive draft through the pipe connection between the hood and furnace.

In testimony whereof I aflix my signature in presence of two witnesses.v
